CLAMPING ELEMENT FOR EXTREME AREAS OF CLOTHES TO BE SUBJECTED BETWEEN
FIELD OF THE INVENTION The invention relates to a fastening element for the end areas of corsetry straps to be fastened to each other, in particular women's undergarments comprising a plurality of textile folds folded substantially one on top of the other, which at least one strap fold contains a fastening element, at least one hook, one eyelet or the like and between two in particular external strap folds fillings are provided to increase the wearing comfort, the filling being applied to at least one of the folds of the belt joining this near the lateral edges of the fastening element.
BACKGROUND OF THE INVENTION This fastening element is derived from US 2 861 276 published in 1958 in which a filling between a back cover that comes into contact with the skin and an additional layer containing the eyelets must be provided. The layer should improve the comfort of the use of the fastening part. To produce this fastening part, all the layers are placed one above the other, separated and then joined with a plastic strap, elastic on three edges. To produce a secure hold, the plastic strap must be machined and pressed under pressure on the closure part. The filling is held only by the elastic outer plastic strap. This will cause the passage between the plastic strap and the outer layer to rest on the wearer's skin and press and rub unpleasantly. The fastening elements are often sewn on the ends of the straps and are generally formed as an eyelet or ribbon with eyelets or tape with hooks. These ribbons of eyelets and hooks can be joined and then together form a closure for a garment. During the making of the eyelet ribbons, the eyelets are often unusually fastened in an arrangement known as an endless base band by stitching. For this purpose, a plurality of the folded calls are sewn in a partially overlapped arrangement on the base tape which is bent on both of its longitudinal sides, the eyelets being fastened on the base tape or the ribbons folded while sewing the ribbons folded together with those for seams that run substantially parallel to the longitudinal sides of the base tape. The base tape together with the bent straps secured thereto is then divided into individual sections forming the eyelet straps by cuts running transverse to their longitudinal direction. In the known manufacturing method, the individual grommets are separated from the endless base belt by the method of thermal welding, for example by the ultrasonic welding method, so that the cut edges of the base tape and the bent ribbons they unite with each other at the same time. This type of cutting of eyelet strips and endless base ribbons or similar endless insulated ribbons is simple in terms of manufacturing technology and correspondingly cheap. However, since the base tape and the bent tapes are separated from each other by cuts directed at right angles to their longitudinal sides, those connecting edges form the longitudinal side edges of the eyelet tape. In the case of undergarments worn directly on the skin, for example in the case of bras whose straps are placed on the skin with some force, there is a risk that the connecting edges of the eyelet straps, which are also placed on the skin, cut the skin. This results in an unpleasant feeling during use, which can lead to skin irritations. The conditions are similar in the case of the hook tapes, for the manufacture of which an endless base tape is likewise used. This is formed first in a type of tube bending this on its two longitudinal sides, slightly overlapping its areas bent inwards and having substantially the same width. The hooks to be arranged in the overlapping areas are fastened to the base tape by means of a similar seam extending substantially parallel to the longitudinal sides of the base tape, with all the layers of the base tape being placed one on top of the other. each other simultaneously. The base tape with the hooks attached thereto is divided into individual sections forming the hook tape by cuts extending in the longitudinal direction as well. Before cutting the individual hook tapes, the base tape is essentially folded in the center around a fold edge extending substantially parallel to its longitudinal direction, and its area containing the hooks over the area that is free. of hooks. If the separation of the tape from individual hooks of the endless base tape is carried out in the same way according to the method of thermal welding, the cut edges of the areas of the base tape located one over the other are connected to each other by the separation operation. Since the cut edges extend at right angles to the longitudinal sides of the base tape in this case as well, those connecting edges also form the front side edges of the hook tapes thus prepared. In this way, the connecting edges of the hook straps also produce an unpleasant feeling during use, which can lead to skin irritations, in the event that the underwear is worn directly on the skin. In order to provide a better wearing comfort in relation to these fastening elements, it is proposed in EP 1 180 948 Bl that a base tape containing a plurality of closing parts, ie hooks, be bent parallel to the longitudinal profile of the tape. base. By this means, the closing parts arrive on the inner side of the folded base tape. The closure elements are then cut from the base tape by separating the weld that runs at right angles to the longitudinal profile of the base tape. By bending over the closing elements thus produced, the closing parts arrive on the outside on the one hand and the sharp edges of the separating weld beads arrive on the internal side of the closing elements. The sharp edges in this way do not rest on the skin and do not produce irritation there. An alternative embodiment of EP 1 180 948, a cover tape is placed on the side containing the eyelets of the base tape. Consequently, the fastening elements are also separated with spacer beads here, and at the same time, the two layers of each fastening element are joined at three longitudinal edges. Here also the acute separation welding cords are brought to the internal side of the fastening element where they do not produce irritation, turning them despite the significantly improved comfort of use, these fastening elements are also not completely satisfactory with respect to the comfort of use. In this way, the object of the invention is to provide clamping elements of the initially specified type, which exhibit better comfort of use despite the fact that their manufacture is as cheap as possible. This objective is achieved by a fastening element of the type initially specified according to the invention, whereby when the fastening element is in the use state, the belt crease is located at least partially between the belt folds. of the fastening element. The objective is further achieved by the method according to claim 12. The invention thus contemplated providing a fastening element with a filler, for joining the filler to the fastener element with a joint and placing the joint, for example with a seam , which is perceived as irritating, between the folds of the strap inside the fastening element. In addition to the previously known generic fasteners, despite the filling, the stitching required to join the padding to the fastener can, according to the invention, be outside the area of contact with the wearer's skin. In the use state of the fastening element, the connection is preferably not accessible and is covered with the folds of the belt. In connection with the invention, the term "belt crease" and "padding" are used to describe endless belts such as those usually used in the manufacture of fasteners and also for sections of endless belts that are cut from belts without end as part of the manufacturing process of fasteners. Particular advantages can be achieved if the padding can be placed in a different position relative to the folds of the belt, preferably by turning over at least two folds of the belt which can be preferably formed as textile folds. By these means, for example it is possible to place the filling (or a filling tape) for its attachment to the fastening element initially on an outer edge of the fastening element, to make the joint and then to have the filling a position between two folds of fastening element strap. In this position, the filling can fulfill its function of relieving pressure particularly effectively. As a result of the inversion, the binding of the filler that is usually irritant, can at the same time be placed in the position between the belt folds. In this position, direct contact between the union and the person wearing the undergarment will preferably not be possible. Another case is that of 2 861 276, for example, where in addition it is possible according to the invention to produce a completely flat contact area between the fastening element and the skin of the user, whereby the contact area of the Clamping can reinforce completely on the skin without any irritating step. In a preferred embodiment of the invention, in this case the filling can be placed in a cavity that is obtained from two strap folds of the fastening element that are joined together. Since it is very difficult and time-consuming to insert the filling manually into the cavity as a result of the textile folds that are hooked with the filling, the process of flipping back / flipping over presents a quick, reliable and yet very simple possibility for the filling arrangement inside the cavity. The padding may preferably comprise a compressible material, such as foamed material, for example that reduces the sensation of pressure perceived by the wearer of the garments in the area of the fastening element. However, in principle, any other material that helps improve the comfort of use for example, fleece material, nylon, velor, microfiber, silicone and others can be used as a filler. Since the two mail or textile folds are preferably joined to at least one joining seam and the joining seam produced before the back flip / flip over process is additionally, at least partly, completely preferably placed in the cavity. . As a result, most of the weld seam has no contact with the skin and therefore does not convince any deterioration in the wearing comfort of the corsetry article. Since the invention preferably relates to fasteners and their manufacturing methods as described in EP 1 180 948 Bl, their content is hereby completely included as a reference. In a preferred embodiment, the joining seam of the belt folds is also used to join the padding to the fastening element. As in other embodiments according to the invention, this application can, on the other hand, reliably avoid the unintentional removal or sliding out of the stuffing of the fastening element or the undesirable folding of the stuffing into the cavity. On the other hand, for a reliable fixing of the filling it is not necessary to completely close the cavity for which an additional operation would be required. Furthermore, in this way all the belt folds of the fastening element can be joined in one operation. If, during the manufacture of the fastening elements, the two folds of the belt as well as the filling tape are placed one on top of the other and at the same time, the respective sections of the respective fastening element are cut from these belts, it is possible to carry out the formation of all the layers of the fastener only in one operation. By means of a separation welding process, the individual folds can be joined together additionally and substantially at the same time using the same simple operation.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES OF THE
INVENTION Figure 1 shows a base tape 1 of an eyelet tape 2 which is provided with eyelets 3 at predetermined intervals. As can be seen from Figure 1, a plurality of bent ribbons 4 running parallel to their longitudinal axis is stitched onto the base tape 1 by means of fastening seams 5 running parallel to the ribbons. The holding seams 5 serve at the same time to hold the eyelets 3 on the base tape 1, whose longitudinal axis runs substantially at right angles to the longitudinal axis of the base tape 1. The latter has thus a region containing eyelets 6 on one side and a region free of eyelets 7 on its other side. The base tape 1 is preferably made of a soft material and can be formed of a flat ribbon whose side regions not shown in detail in the figure are folded over one another and overlapped by a certain amount. The base tape 1 thus forms a tubular structure with overlapping edges. An establishment ribbon 8 can be provided within the base tape. In this case, the setting tape 8 simply has the function of imparting greater rigidity to the base tape. The laying belt is preferably located completely within the base belt 1 and is bonded thereto as a result of the fastening seams of the fastening parts. The upturned edges 18, 19 of the base tape 1 form the two front boundaries of the buttonhole tape 2 relative to the position of use of the buttonhole tape 2 when used in bras. As can be seen from Figure 1, a preferably elastic cover tape 10 which covers the eyelets 3 is placed over the region containing the eyelets 6 of the base tape. In the case of the exemplary embodiment, the cover tape 10 consists of Lycra (Dupont Trade Mark) or a material having comparable properties. A filling tape 20 is placed on the side of the eyelet-free region 7. In the exemplary embodiment the filling tape 20 consists of foam. Preferably, as in the example shown, this may comprise a synthetic weldable foam. These foams are distributed, for example, by Recticel, Belgium. With reference to the cover tape 1 with folded ribbons stitched on top 4, the cover tape 10 is thus on one of its sides and the filling tape 20 on its other side. In this position of the base tape 1, the cover tape 10 and the filling tape 20, a thermal welding process is used, for example, an ultrasonic welding process for cutting consecutive sections of predetermined length of the base tape 1, the cover tape 10 and the filling tape 20. The length of these sections determines the height and width of the buttonhole tape, for example in a bra, in relation to the position of use of the buttonhole tape 2 has to be produced
The separation welding tool to be used (not shown) can thus be made so that during the separation process, it forms a welded seam 21 or 22 in both a first section and a second section after it. Optionally, a transverse weld can also be formed between the two welded seams 21, 22, so that the spaced section is at least substantially enclosed in the area of three of its side edges. The cut edges of the buttonhole tape thus formed are then welded with the cut edges 24 of the cover tape 10 and the cut edges 25a of the filling tape 20. Among other things, these welded seams have the function at least in part to form a joint between the padding and at least one of the belt folds that fix the padding on the fastening element. This results in each case in a reinforced and very well defined joining edge 26 which is located on the respective external side of the corresponding section. In each case, the eyelets 3 always remain covered by the cover tape 10 which is now welded on top. As a result of the next process of flipping up / flipping back, the section is turned up again so that the cover tape 10 is brought from the region containing eyelets 6 to the free region of eyelets 7. both the buttonholes 3 are exposed. At the same time, the joining edges 26 (the loosening seams) are brought inside the finished buttonhole tape, so that the two border edges 27, 28 of the buttonhole band 2 , which come into contact with the skin in the position of use of the buttonhole tape, are substantially formed by the cover tape 10. At the same time, the separation section of the filling tape 20 is put as a filler between the tape of cover 10 and the base tape. In this case, the filling is fixed to the fastening element thus produced in three or four lateral edges via the holding edge 26. It is not necessary to insert the filling into the cavity 29 formed by the separate tapes of the covering tape 10 and the base 1 tape and there is no risk of the filling being intentionally removed from the cavity. The buttonhole band 2 thus formed can be sewn in a manner known per se on the strap of a garment, for example, on the strap of a bra. In this case, in relation to the position of use of the bra, the two non-limiting edges form the upper and lower region of the buttonhole tape 2 sewn on the strap. Preferably, as a result of an increase in the compressibility of the fastening element according to the invention in relation to its thickness, the comfort of the use of the garment can be increased with the filling. The individual fastening portions and the joining seam can press through it on the skin to a lesser degree with the fasteners of the invention and therefore are poorly perceived by the wearer of the garment. Figure 4a shows the different endless belt plies of an exemplary embodiment of a hook tape 32 which is provided with hooks 33 at predetermined intervals. These hooks are fastened on the base belt 31 by means of a fastening seam 34 running substantially parallel to the longitudinal axis of the base belt, its longitudinal axis running (longitudinal extension) substantially at right angles to the longitudinal axis of the base belt 31 The hooks 33 are stitched onto the base tape together with a folded ribbon 36. In the exemplary embodiment, the base tape 31 is completely bonded once around an establishment tape 39, whereby the two side regions of the base tape 31 are superimposed on the side of the hooks of the base tape and rest one on top of the other. The setting tape 39 is thus completely arranged within the base tape 31. The upper side region of the base tape 31 with the hooks 33 is located on the upper side region and could be hit upwards., inwards, again to form a clean border. The fastening seam 34 serves at the same time to fix those folds of the base tape 31, which in turn forms a tubular structure with overlapping splice edges. The upper lateral region thus forms a region containing hooks 37, while the inner lateral region forms a hook free region 38. In principle, regions 37 and 38 can be of different sizes or of the same size. As shown on the right hand side of the diagram in Figure 4a, the cover tape 30 is parallel on the base tape 31 with stitched hooks on top and bent ribbons stitched on top 36, the cover tape preferably comprising elastic material such as Lycra, example. The base tape 31 as well as the hooks 33 are covered by the cover tape 30 and thus are shown by dotted lines in this part of Figure 4a. The filling tape 40, which can be identified to the left of Figure 4a, is located on the other side (in the diagram in Figure 4a, the inner side pointing towards the surface of the drawing) of the base tape. The filling tape 40, for example, made of elastic compressible foam, preferably has the same width as the base tape 31 when it is folded. From bottom to top, the filling tape 40 rests in this way against the base tape 31 containing the hooks 30 and this base tape 31 with the folded tape sewn on it is spliced against the cover tape 30. In this position of the regions 37 and 38, and the filling tape 40, the successive sections of predetermined length are separated substantially simultaneously from the base tape 31, the filling tape 40 and the cover tape 30 by means of a thermal welding method, by example, by means of ultrasound. That separate section is shown in Figure 5. The length of those sections determines the height or width of the hook tape 32 relative to the position of use of the hook tape 32 to be produced, for example, in bras. The separation welding tool (not shown) to be used for this purpose can thus be made so that during the separation process, it forms a separation welding posture 41 both in a first section and in a second section afterwards. this. The cut edges 42 of the formed base tape are therefore welded to the cut edges 43 of the cover tape 30 and the filling tape 40, in each case forming a reinforced and very well defined binding edge which is located on the respective external side in the corresponding section. In this case, the hooks 33 always remain covered by the cover tape 30, which is indicated by the dotted lines for the hooks 33 and the folded edge of the folded ribbon 36 in Figure 5. As a result of a following process of flip up / flip down, the separate section is flipped up / flipped down around the part of the binding edge 41 opposite the opening (side edge 49) of the cavity in such a way that, on the other hand, the hooks 33 are released from the cover tape 30 and on the other hand, the joining edges 45 (separation welding) are placed on the inside of the hook tape 32 (Figure 6). By these means, the two limiting edges 47, 48 of the hook tape that do not come into contact with the skin in the position of use of the hook tape, are formed by the material of the base tape 31. At the same time, the separate sections of the filling tape 40 that are welded to the hook tapes lie between the base tape 31 and the cover tape 30. In this exemplary embodiment the previously separated sections of the base tape 31 and the cover tape form the cavity with its part open along the side edge 49 in which the section of the filling tape 40 formed as a filler is located.
The hook tape 32 thus produced can be sewn in a known manner on the strap of a garment, for example, on the strap of a bra. In this case, the two limiting edges 45, 48 form the upper and lower region of the hook tape sewn on the belt, in relation to the position of use of the bra. It has been assumed here that a separation weld seam was formed respectively when the individual sections of the hook tape and the buttonhole strip respectively in both sections were separated. This can be achieved by using a relatively simple separation welding tool. In addition, any waste of base tape is avoided in this case. However, it is of course also within the scope of the invention to use a forming / spacing welding tool respectively, for cutting into the individual sections of the hook tape or the eyelet belt. In this way it is possible to form the two separation welding seams respectively at the same time on the respective section. The separation / forming welding tool used to cut the sections of the base tape or the hook tape over the buttonhole tape then need only be provided with two rectilinear sonotrodes to be arranged at the distance of the length of the individual sections. To cut the sections of the base tape of the eyelet strips it is possible to use the sonotrodes substantially U-shaped or a separate, U-shaped cutter, whereby the two longitudinal separation seams and at the same time the welding of Cross-sectional spacing that extend between them can be produced at the same time. The transverse separation weld bead can alternatively be formed as a normal weld bead, that is, as a spacing weld bead. In another embodiment, a fastening element can be separated from the belt folds using separation tools comprising a single sonotrode and a separation cutter. In this case, one of the two longitudinal separation welding cords is formed in the cutting region both in the fastening element that is currently being cut and in the next successive fastening element. For example, by locking the cut-off element 90 °, the transverse separation weld bead sequentially formed, using the same or a second separation tool (sonotrode and separation cutter). To achieve a uniform edge profile that is as narrow as possible, the material projecting from the belt folds in the transverse separation weld bead can be cut. It is therefore possible to prevent the transverse separation weld bead from rising up / backward in the cavity from rising. As a result of the process that has been described, a reinforced clamping edge is formed in the region of the corresponding upturned edge, which may initially be considered as disadvantageous. However, since this clamping edge lies between the eyelet-free region and the cover tape or the filler tape as a result of the process of flipping up / flipping back the eyelet band, the clamping edge does not it has a negative influence on the comfort of use. At the same time, the advantage is achieved that the corresponding upturned edge is reinforced.
